My 1:1 tests of TT2 vs Wavelight are done and the product goes to Classifieds. If someone is interested it is a good moment to look here.

Since I have promissed to provide some feedback I will try to drag a conclusion. TT2 are Wavelight are the best DACs I have ever heard but also sound very different. They are quite opposite as presentation.

I have used only one pair of headphones, Final Audio D8000 Pro, since I am an exclussive headphone listener (my tube amp does not have outputs). The source was my PC where I have a JCAT Femto XE externally powered by a Sbooster 5V LPS. The USB cable is a Kimber Kable USB-Ag. I tried several interconnects (Lavricables Grand 20 Core Silver XLR, Neotech NEI-2001 RCA (handmade by a professional), DH Labs Air Matrix) and 2 headphone cables (FAW Noir Hybrid and Lavricables Grand Silver). My listening session took around 200 hrs (but tests only several hours, more was accomodation to the new signature). Comparison was made with Chord Hugo TT2 connected with M Scaler with full upscaling, powered by MCRU Ultimate power supplies and Dual-BNC connection via Wave Storm cables. TT2 and M Scaler power supplies are inserted in a Furman AC-210A-E. All audio equipments are connected to a Kemp power strip and that one in an Audioplan Fine Filter S which is plugged into the wall. I gave all these details to let people understand a little bit the environment where Rockna Wavelight was tested. This one was plugged directly into the Kemp power strip since I did not want to remove TT2 and M Scaler from their own custom supplies and was kept powered ON all the time. As for the music, I listen exclusively to rock/metal. For the evaluation I have used 4 albums I recently listen to: Katatonia - Sky Void of Stars, Riverside - ID.Entity, ...And Oceans - As in Gardens, So in Tombs and Gamma Ray - Empire of the Undead. These were diverse enough to let me form an opinion.

I will not make a review, I'll just explain why for me the decision was to keep TT2 in detriment of Wavelight, this being an information I was asked for.

And now let's begin. From the first listening hours I have observed that Wavelight had a more rounded presentation, somehow smoother and rolled off in the treble. At first this gave me the impression of a more analogue presentation, a more organic one, but later I started to miss the high frequency extension of TT2 which was for me airier and sounded more lively. It was a fluid sound, and the softer signature was less fatiguing than the one of TT2, I was able to turn the volume to a higher levels and listen without any problems. But in my usage scenario TT2 is not quite fatiguing, at least in my setup when used with a custom tube amplifier and a quite big variety of tubes which allow me compensate. The softer and more fluid presentation came with a flaw, less dynamics. Everything was sounding to me slower, and this was evident to me on the Empire of the Undead track where I had a feeling of slow motion.
Regarding detail retrieval I find TT2 more resolving and with better instrument separation, and this was easy to see in the more intense tracks of ...And Oceans. On the slower songs of Riverside the more analogue and fluid sound of Wavelight was maybe better but even in that case, the treble roll off made it sound more sterile and unengaging compared to TT2 which was more energetic and emotional while keeping a more technical presentation because of better detail retrieval and airier sound. I know, this is not a very audiophile term but in the end what we all seek is pleasure in listening.
I started to think if I can compensate the lack of engagement and speed with different cables and I obtained interesting results. While all were close, the best from all was the Neotech NEI-2001 hand made one, which sounded the most lively to me and had the best extension on both ends. With it the music was alive while on others I felt it was just a recording. And regarding headphone cables, the Forza Audioworks Hoir Hybrid was better than the Lavricables Grand Silver for the same reason. So in conclusion I made a longer listening session of Wavelight with these ones to be sure that I am not judging it with cables which are not fitting my preferences. In this configuration my previously mentioned flaws were minimized but still, there was a margin to TT2 level which made me take the decision I've mentioned.
Now, in the end, I have to repeat what I have already said. I am not an usual listener, I have a very specific setup and I have some very specific expectations. And this is the reason I have most probably a different experience as others here. I do not want to deny theirs, nor consider mine more relevant, but I felt it was my duty to present my honest thoughts to the community. Another important aspect is that rock music is a complicated genre. You have distorted guitars, keyboards and all kind of vocal performances in a quite fast and intense song. I felt that Wavelight was exceptional for acoustical music and the lack of dynamics were inexistent on slower tracks. But for me this was no help, I listen to fast music where a sharper sound is more engaging. I felt Wavelight was removing emotion and lively sound from the music with that softer presentation, and this was a no go for me. What I enjoyed more was the incredible good build quality, the Android remote app and the overall solid and fluid sound it was providing. But this sound was, at least for me, lifeless.
On the TT2 side I have to mention that my setup had incremental upgrades and I felt that they had a major impact on sound quality. In other words, I had to build a whole ecosystem for TT2 to sound as it sounds now (LPS, filtering, USB with JCAT, Wave Storm DBNC) and Rocka Wavelight plugged directly into the power strip sounded close. Close but different and I doubt I can make it go into the direction I want regardless of the additional investments as the server. This was something I really wanted to try and I will miss in the future.

Ok, this was my testimony, I do hope it will provide an interesting point of view for others and please excuse my lack or reviewer skills. I'm an engineer, most probably a failed one, since I work in a totally different area now.
Did you try M Scaler into Wavelight to compare that to M Scaler into TT2?

Thx for the reasoning. I was surprised by the decision but the explanation made sense

I have not tried it, I thought it did not make sense since my decision was to keep TT2+M Scaler or Wavelight. More than this, Wavelight, which was used on Linear filter (I missed to mention that because all filters are almost the same on my system, just like the ones of TT2), has already an 8x upsampling. From what I understood only NOS has no oversampling. I might get it wrong but 8X for 44.1KHz is half of what M Scaler does for TT2 (705KHz). But if I connect M Scaler to TT2 I obtain half of that using single BNC because only TT2 accepts Dual BNC, so in the end I have the same upscaling level. I'll dig into that and try that if I have time and Wavelight is still here.

Everyone ears are different, for me this is the best way.

The USB cable is a Kimber Kable USB-Ag. I tried several interconnects (Lavricables Grand 20 Core Silver XLR, Neotech NEI-2001 RCA (handmade by a professional), DH Labs Air Matrix) and 2 headphone cables (FAW Noir Hybrid and Lavricables Grand Silver).
Was the Kimber Kable worse than the Neotech NEI?

Also heard good things about Oyaide Continental 5s V2 which is silver also.

No. Kimber Kable USB-Ag was used to connect the DAC to the source. I have several USB cables but never changed this one.
Neotech NEI-2001 is an interconnect cable and was the best for me from the 3 pairs I have tried here. This one was the best from several pairs back in the day and this is the reason is my main interconnect for TT2 for several years. However, this was a DAC test and I have not spent equal time with all the interconnects, my plan was to make an 1:1 DAC test using the best cables and equipment I have around. So take with a grain of salt the interconnect discussion because it is only a side topic, not the main topic.

Hi thanks for the feedback! Even if always looking for sound optimization I somehow get bellyaches to spend $1.5K for an USB cable to my DAC. But in hifi the term “expensive” is relative.

Maybe there are other good silver USB cables that get similar results 🤔 with less investment?

So after trying every kind of combination possible. A fuse soldered onto the PCB board using a 18 gauge Mundorf Solid Silver Gold wire gives the highest level of detail and almost perfect life like timbre. This DAC is operating at perhaps 80% of it's capability without this mod.
I know that sounds like a massive exaggeration, but if anything, I am understating it.

Have to agree with everyone else, this DAC is very sensitive to any changes that you made further up in the audio chain.
I am in Audio Nirvana at the moment....the capacitor upgrades will also be coming at some point :)
Ok so I bought the same Mondorf silver gold 18ga wire and performed the same surgery on my WL. Fuse holder is out and my qsa fuse is hard wired. To be honest, I was not expecting to hear any difference. I tested continuity to make sure everything was good. Plugged it in, turned it on and walked away for 8 hours. @batmansbest, you weren't joking! I'm not sure how to quantify th 20% improvement. you mentioned, but dam it the dac sounds more realistic. So musical, to me it's as if a veil was lifted. My digital pretty much out performs my analog rig. So amazing!

Though it has been quite sometime since I've heard either dac but oddly enough from what I recall the one aspect I find the Wavelight excel in is dynamics. The presentation is more laidback than the tt2 and definitely a smooth sounding dac but it is far from inexistent. Perhaps it's the way we use dynamic to describe sound. The more upfront sounding tt2 does have a more pronounced slam than the laidback sounding wavelight. But a dac lacking in dynamics sound flat and compressed and to that the wavelight is very far from it. It slams real hard when the tracks calls for and but is also able to resolve all the tiny modulation that exist within the tracks. To my ears the wavelight have some of the best dynamics I've heard in this price range.

Not saying you're wrong in your observation or anything of sort just pointing out the differences in the way we hear and appreciate you spending time to write down your thoughts.

Music sounds incredible. Definitely Musical.....and the resolution, it's up there also.
Such a simple cheap mod, you know people spend tens of thousands of dollars to get marginal upgrades, and stuff like this...it's incredible.
I would love to compare this modded wavelight to a stock wavedream (and especially after a capacitor upgrade), see how it measures up :)

I am recommending this tweak all the time, it kills some audiophile marketplaces. :)

One note. I would use shorter legs, in order to place a fuse flat, close to the board as much as possible. It reduce inductance to a minimum. But once it is done, leave it as is, not a big issue.

I tried every which way, short and long leads. This sounded the best to my ears.
The silver gold wire also gives a change in tonality to the overall sound.
Instrument timbre is more realistic, and there is more air in the recordings, and no upper mids stress like this DAC had before.
18 gauge Solid OCC copper sounds more flat, congested, and more saturated in comparison.

The connecting wire is extremely important in my experiments. 20 gauge sounds very thin and shouty. 18 gauge is the Goldilocks zone on fuses, at least in my system.

Thank you for this suggestion. It's really transformed my system as a whole. Just incredible...

The fuse in the picture is one that I made myself, using OCC silver filaments, and the cylinder is filled with heat sink paste. Both ends soldered into the endcaps.

My USB cable and Interconnects are also made using Mundorf Silver Gold 17mm foils. All homemade of course :) It really has the best timbre and presentation.

Oops, I didn't know you tried many combinations. A final effect is important, good work.

I used the exact same Mundorf Silver Gold 18 Ga, as well as about the same length, I completely agree, the top end is just incredible cymbals and hi-hats sound more 3 dimensional with shimmer, but no glare, or edge. My fuse is the QSA violet, and improvement is profound!

Same results as I got. Crazy how you can tune this DAC by changing these 2 little pieces of wire. The resolution on the shimmers and cymbals is amazing, they pop in 3 Dimensional space, and zero harshness anywhere. The Audionote capacitors, especially in the Preamp section, should give the sound a beautiful texturing.
Give this DAC extra layers.
I'm glad that you like it. Most people would not be brave enough to tinker with this kind of a mod.

Another observation .
HQPlayer playing files directly through it's UI sound quite a bit better, than using it through Roon. The difference is surprisingly quite big.
To my ears, direct sound, zero upscaling, sounds the best.
From what I read from other people's impressions, the Holo May is the exact opposite.

Beethoven symphonies, Pittsburg orchestra DSD, sounds just incredible. The instrument timbre, layering, textures, 3D presentation, it's just a joy to listen to.
What a wonderful piece of Tech.
